The win condition revolves around summoning
4 level 1 monsters on the field, to then summon
Assembled Nightingale and Recital Starling, in sequence, to buff Nightingale with Starling, then
attach it using Bird Sanctuary, to end up with a 1600 attack, 5 material Nightingale on the field, just enough to OTK a starting health player.
Note that there are
very bricky combinations of hands in this deck due to the nature of the arquetype, and thus it is not very competitively viable, but you can still reach mid platinum if played well.
Main Strategy:
It is a deck that is similarly strong when played first or second, but has different weaknesses for either. When going first, you are at the risk of being Kaiju'd (or other similar effects) on your opponent's first turn, excluding your boss monster from the field, and being at the mercy of your opponent, but if playing second, your opponent can have many negate monsters and/or traps to break your combo, which would leave you in a very vulnerable state.
In your starting turn, what you want to do, is generally to try to special summon both Cobalt Sparrow and Celestine Wagtail, although the latter isn't neessary if you drew Bird Sanctuary. You can do this using the effects of Bird Call, Turquoise Wabbler, Saphire Swallow, One for One, Summon Storm, Swallow's Nest, and from the GY with Beryl Canary and Turquoise Wabler. Then search for either monsters to extend your combo, or Bird Sanctuary to finish it.
